Kuch Kuch Hota Hai (English: Something Happens) also known as KKHH, is an Indian Hindi coming-of-age romantic comedy drama film, released in India and the United Kingdom on 16 October 1998. It was written and directed by Karan Johar, and starred the popular on-screen pair of Shah Rukh Khan and Kajol in their fourth film together. Rani Mukerji featured in a supporting role, while Salman Khan also had an extended-cameo appearance. Sana Saeed, who was featured in a supporting role, made her film debut in this movie.
Filmed in India, Mauritius, and Scotland, this was Karan Johar's directorial debut. One of his goals for the film was to set a new level for style in Hindi cinema. The plot combines two love triangles set years apart. The first half covers friends on a college campus, while the second tells the story of a widower's young daughter who tries to reunite her dad with his old friend.
The film was extremely successful in India and abroad, becoming the highest-grossing Indian film of the year and the third highest-grossing Indian film ever behind Hum Aapke Hain Koun..! and Dilwale Dulhania Le Jayenge. The film was also the first Bollywood film to enter the UK cinema top ten. Outside India, the film was the highest grossing Hindi film ever until its record was broken by Karan's next directorial, Kabhi Khushi Kabhie Gham... (2001).
Kuch Kuch Hota Hai received a positive reception from critics, with special praise directed to Kajol's performance. The soundtrack also became the biggest seller of the year. The film won many major awards including the National Film Award for Best Popular Film Providing Wholesome Entertainment and the "Best Film" honor at the Filmfare Awards, Zee Cine Awards, Screen Awards, and Bollywood Movie Awards. The film won 8 Filmfare Awards and is the only film in history to win all the four acting category awards at the ceremony (Best Actor, Best Actress, Best Supporting Actor & Best Supporting Actress).
